Hi Ulrich, there was a Data Stores system session earlier today which may have caused issues, see:

Can you retry your request, please?

Hi Kevin,
Thanks for your message.
I have just retried with the same error message and result as before.
As a fun fact, all other years and month between 2016 and 2025 have been processed for **fal** without issues.

Hi Ulrich,
I was able to run your request and download the data file (via web and API), so I’m wondering if its the CDS cache issue, whereby resubmitting a request retrieves (or tries to) the data file from the cache. If you change your request slightly it should result in the data being re-extracted and a new file placed in the cache for download; see:

HTH,
Kevin

Hi Kevin,

I always deleted the request before - would that still be the case then.

but I will try.

thanks, Uli

Hi Uli,
Even if you delete the request, the data stays in the cache for a few days until it is automatically removed by the CDS system,
Thanks,
Kevin
